Sensors are the core components of drone flight control systems, which can help drones achieve multiple functions such as attitude control, navigation, and flight control. The data provided by the IMU is used to generate control instructions and adjust the flight attitude of the drone to maintain stable flight.
ERICCO's IMU ER-MIMU-07 is a nine-axis IMU with a three-axis gyroscope, a three-axis accelerometer, and a three-axis magnetometer.
Gyroscopes and accelerometers provide angular velocity and acceleration data, which can be used to calculate information such as the attitude, speed, and displacement of the drone.
The magnetometer can provide data on the magnetic field to which the drone is subjected and provide the direction of magnetic north.
So what are the advantages of this IMU?
**High-precision sensor**
The built-in gyroscope has a measurement range of 400º/s, bias instability (1σ 25℃) <0.3 º/h, and angular velocity random walk <0.125°/√h. The accelerometer has a measurement range of 30g, bias stability (10s 1σ) <50ug, and bias repeatability of 100ug.
The measured data supports the flight control system to detect the attitude changes of the drone in real time, so as to quickly respond to unreasonable body attitude changes. The data provided by the IMU, combined with other sensor data, helps determine the position and direction of the drone.
**Small and easy to install**
The volume is only 38.6x 44.8 x25.5mm, and the weight is ≤70g. The compact and small design can be easily installed on the fuselage of the drone.
**Better performance, lower price**
This IMU simplifies and reduces design costs while maintaining high performance. Its performance is better than STIM300, but the price is lower, which helps reduce the cost of drones.
To sum up, IMU is an indispensable part of the UAV flight control system, ensuring that the UAV can fly stably and perform flight tasks accurately.
